    Before buying ergonomic products, think the question such as:
•    Does the design and the manufacturer's claim make sense?
•    What research has the manufacturer done to support their claims?
•    Does it feel comfortable to use the product for long periods of time?   Sometimes it takes a little bit of time for a product to feel comfortable and "break in" or change your posture in order to become beneficial.
  •    If it hasn't' been recommended by an Ergonomist, don't use it.
